LVDT Transducer Selection Guide | LVDT Transducer Manufacturers

The page describes LVDT Transducer Selection Guide including popular LVDT Transducer manufacturers. This guide helps in selecting appropriate LVDT Transducer from multiple Manufacturers.

What is LVDT Transducer?

Introduction:
The device LVDT (Linear Variable Differential Transformer) is an electrical transformer used to measure linear displacement or position. There is another device RVDT which measures rotary displacement.

LVDT transducers are robust and frictionless. Moreover they has lower hysteresis and better repeatability. LVDT does not require physical electrical contact between moving part and coil assembly. It just depends on electro-magnetic coupling for its operation.

Position and displacement may be sensed by methods of electromagnetic induction. A magnetic flux coupling between two coils may be altered by the movement of an object and subsequently converted into voltage.

LVDT transducer has measurement range in between +/-100 µm to +/-25 cm. The input voltages are in the range from 1 V to 24 V rms.
